Animal welfare and herd health focuses on understanding and providing for animals’ behavioral needs, promoting positive human-animal interactions and assessing animal welfare and improving animal-environment fit.
Dr. Jennifer Van Os’ research focuses on understanding and improving dairy animal welfare, particularly by identifying low-barrier solutions.
Prototheca bovis has been cultured in herds and is emerging as a threat to producers statewide. Prototheca has been linked to mastitis since 1952, however, within the last five years, the prevalence has significantly increased. Similar to Staph aureus and mycoplasma, Prototheca is hard to detect, has no known cure, and is contagious by intermittently shedding from cow to cow.
Animal care and welfare starts on day one with the newborn calf. Healthy calves are the cornerstone of every dairy operation, not only providing the future genetics for the herd but healthy calves are also important to the vitality of the dairy farm.
Superior calf performance begins during the birthing process in the maternity pen. Based on the 2017 USDA NAHMS Survey, five to seven percent of all newborn calves are stillborn or die within the first 48 hours. To improve calf survival after birth, we must follow practical, consistent calving protocols and provide a clean, dry calving environment.
One of the simplest best management practices we can do for the newborn calf is navel care. Previous University of Minnesota research showed in a controlled study that umbilical cord care significantly reduced the risk of developing umbilical cord infections.
As operations grow, or focus more on the milking herd, it has become a necessary component in moving newborn calves from the farm to a separate calf raising facility, some being out of state. Handling and transporting these calves can be stressful. However, there is limited research on the impact of long-distance travel on a newborn calf’s welfare.
Hoof health is essential for not only the overall health of the animal, but also for her welfare. Digital dermatitis (DD), or hairy heel warts, is an extremely painful condition for dairy cattle, reducing their ability to walk to and from the milking parlor, or to the feed bunk. Based on USDA NAHMS 2017 data, 16.8% of all cows and 2.6% of bred heifers have lameness on a dairy operation.
By Donald C. Sockett, DVM, MS, PHD, DACVIM (large animal); Wisconsin Veterinary Diagnostic Laboratory, UW-Madison It is important for livestock barns, calf pens, and calf feeding equipment to be properly cleaned before the disinfectant is applied. If surfaces are not properly cleaned, the disinfection step is much less effective at killing disease-causing microorganisms. Many disinfectants […]
English | Spanish El tiempo caliente puede traer una larga lista de problemas para las productoras lecheras. Cuando las vacas están sobrecalentadas, se comen menos, producen menos leche, tienen función inmune reducida y recuento de células somáticas levantado y muestran fertilidad reducida. Un aumento en vacas cojeras frecuentemente sigue la temporada de calor. En olas […]
English | Spanish A medida que aumentan las temperaturas de verano, las vacas lecheras corren un mayor riesgo de sufrir el sobrecalentar. Las vacas sobrecalentadas sufren de una ingesta reducida de pienso seco, lo que lleva a una producción de leche reducida. Los agricultores también pueden ver una reducción de la fertilidad o la pérdida […]
